  A special dryer for sodium hyposulfite refers to the removal of moisture through a stream of hot gas that flows in the opposite direction through a small particle. When drying large quantities of bulk powder, it may be important to better control the output characteristics of the powder. The temperature product can be dried in a few seconds even at elevated temperatures. Process parameters such as classifier speed and outlet temperature can be adjusted to control the water content and particle size of the final product. The water content in suspensions, slurries, pastes, doughs, filter cakes and wet powders fluctuates from a few percent to over 80%. Can be used in different industries, such as food industry, chemical industry and pesticides, inorganic pigments and fish feed products.
